Get image width while uploading image PHP - php

Question

in my code, while a user is uploading a pic, in my php code i want to read the width of the image while its getting uploaded, below is my code --
<?php
require_once('config.php');
$file_path = $_SERVER['DOCUMENT_ROOT']."AndroidApp/VideoUploads/Thumbnails/";
$emailid=$_GET['emailid'];
$randNum=$_GET['randNum'];
$ext = findexts ($_FILES['uploaded_file']['name']) ;
$thumb_url="DoUpNow_Funny_Video_Thumb"."_".$randNum.".".$ext;
$file_path = $file_path.$thumb_url;
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path) ){
list($width) = getimagesize($_FILES['uploaded_file']['tmp_name']);
$stmt2 = $linkID1->prepare("update VideoUploads set video_thumb=?, width=? where emailid=? and randNum=?");
$stmt2->bind_param("ssss", $thumb_url,$width,$emailid,$randNum);
$stmt2->execute();
$stmt2->close();
echo "success";
} else{
echo "fail";
}
function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
}
?>
The file is getting uploaded, but there is no value in the width variable, is anything wrong, or my approach is wrong.

Answer 1

After move_uploaded_file(), the tmp_name variable refers to a file which no longer exists, it was moved.
If the file is valid, it will be moved to the filename given by destination.
So, use $file_path to get your file informations :
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path) ){
list($width) = getimagesize($file_path);

Answer 2

try this code it's working fine
check this and let me
<?php
$image_info = getimagesize($_FILES["uploaded_file"]["tmp_name"]);
$image_width = $image_info[0];
$image_height = $image_info[1];
?>
